The purpose of this post is to exemplify in what I believe to be, the desperate need for a centralized approach to managing medium and large scale enterprise networks. I am so used to people parroting entrenched enterprise networking vendors explain all of the reasons why centralization would never work I don’t bat an eyelash anymore. All the while the same manufacturing naysayers are making huge profits on centralized 802.11 wireless delivery. The fastest growing space in the average medium to large campus network is wireless with a centralized controller. Collapsing forwarding and RF management into one or more centrally managed and orchestrated Borgs has been the only thing that has kept large scale 802.11 Ethernet deployments coming close to a functional service. “The idea that one generic controller will be able to control every forwarding decision on a plethora of network types is seductive, but in the end unlikely.  The idea that many applications on many types of controllers can integrate and optimize local forwarding decisions is compelling and well grounded in history.” -History as a guide to SDN’s coming evolution http://blogs.cisco.com/getyourbuildon/history-as-a-guide-to-sdns-coming-evolution/ [...]
